Series: Measuring What Matters
You can't optimize what you can't verify.
In a world of fragmented channels, privacy regulation, and measurement chaos, marketers need proof. That proof starts with attribution match rates and ends with ROI clarity.
If your attribution match rate is under 70%, you’re optimizing guesses, not conversions. Brands in high-volume verticals like QSR and CPG are now achieving 70–90% match rates and using that clarity to drive real lift, not modeled estimates.
What Exactly Is an Attribution Match Rate?
Attribution match rate represents the percentage of exposed individuals you can deterministically link to conversions, such as store visits or online purchases.
When match rates are low:
-
Your ad exposure remains anonymous
-
Attribution becomes fragmented
-
Optimization decisions rely on inference rather than proof
According to the 2024 State of Attribution Report by MMA Global and Neustar, identity-first attribution systems deliver 20–30% higher accuracy than cookie-based models.
Why It Matters for High-Volume Brands
QSR Example
A fast-casual franchise client using AiOpti’s Super AIdentity Graph℠ achieved a 70%+ match rate, enabling accurate store visit attribution across local outlets.
CPG Example
A growing CPG brand improved cross-channel sales attribution by 2.3× by linking CRM purchase histories to digital exposure.
These results reflect a broader industry shift toward precision measurement. When you can tie exposure directly to outcomes, without guesswork, you gain the power to suppress waste, reallocate spend, and validate lift.
The Problem with Third-Party Segments
If you’re still relying on third-party segments or IDs, here’s what’s happening:
-
You’re missing repeat customers not linked to a device
-
You’re overestimating modeled lift in specific channels
-
You’re leaving offline sales and visits out of your measurement strategy
Third-party IDs don’t tie back to people. They tie to devices, and those devices are deleted, expire, or are shared across households.
CustomerLabs and AdExchanger confirm that most vendors still operate below 45% match rates in real-world use, leaving vast attribution gaps.
AiOpti’s Identity-First Attribution Stack
We help brands close the match rate gap by stitching together verified first-party signals:
-
Hashed emails from loyalty and CRM programs
-
E-commerce transactions and POS credit and debit card transactions
-
Location data that maps exposure to real-world visits
-
Timestamped ad impressions tied to conversion events
This results in:
-
70–90% attribution match rates
-
Verified linkage of ad impressions to store visits and purchases
-
Real ROI modeling from spend to outcome, not proxies
Spend-Based Attribution Starts With Match Rate
Match rate is your foundation. Spend-based attribution is the outcome.
When your match rate is over 70%, you can:
-
Validate exposure → visit connections
-
Suppress current customers and save spend
-
Drive uplift modeling using real outcomes
-
Compare media partners by actual performance
When your match rate is under 50%, you’re optimizing noise.
Global Validation: Avaus Study
Avaus, a European data science consultancy, recently shared how one global brand increased match rates from 20% to 80% in just 90 days, boosting ROAS by 30% and generating 20% incremental revenue through first-party identity investments (Avaus blog, April 2024).
These results mirror what AiOpti delivers to fast-growing franchise and CPG clients in the U.S. market.
